The Wire library is a part of the Arduino core libraries and provides an easy-to-use interface for I2C communication. I2C is a serial communication protocol that allows multiple devices to communicate with each other using a single, shared bus. The Wire library simplifies the process of sending and receiving data over I2C, making it a popular choice for Arduino projects that require communication with I2C devices. void setup() { Wire.begin()
